    What is the difference between single phase and three phase motor
    Why we use a capacitor in single phase but not in three phase motor?

    One purpose is to delay energy to one of the motor coils to increase starting torque in single phase motors. The nature of 3 phase power provides the necessary torque.

    See Wikipedia: AC motor, Wikipedia: Electric Motor, HowStuffWorks: How Electric Motors Work, and All About Circuits: Single-phase induction motors.
